PREVENTING FOUNDATION PROBLEMS


Foundation experts have always said, if you could keep the soil around your foundation moist, you could avoid foundation problems resulting from contracting and expanding soil. Studies at the University of Texas at Arlington have proven this theory to be true. UNTIL NOW the problem however, has been the lack of a system that could deliver a small controlled amount of water evenly.

Now, through modern technology, a product has been developed for just that purpose. This product is Foundation Guard™ and is only installed by our skilled team. Once Foundation Guard™ is installed; it will slowly replace and maintain the moisture around and underneath your house. This is an excellent method of preventative maintenance as well as correcting minor structural disturbances. As the soil accepts this moisture, it will expand to its original volume. This expansion can have a tremendous effect on correcting cracked slabs and footings, as it exerts up to 1,500 psi in upward pressure. Because of this upward push, the correcting of an uneven slab and closing cracks in walls is possible. Special care must be taken to prevent over-watering or rapid injection of water which can cause just as extensive damage as under-watering.

In the greater Houston area and for that matter most of the South we have a variety of soils, the most common is referred to as “Gumbo”. This tight, fine particle clay shrinks at an average rate of ¾ of an inch or more per cubic foot. The depth of this “Gumbo” ranges from 2 feet to about 15 feet as our top soil.

Moisture under foundations is depleted from the outer perimeter inward, creating a partial void underneath the outer perimeter of the slab. This results in a decrease in the upward pressure of the soil and in turn results in the lowering of the outer perimeter. The traditional method of foundation repairs when this happens has been the “Piering System” which replaces the hydrostatic pressure of the soil with a concrete pier to artificially raise the slab to its original height and provide future support in case the hydrostatic pressure is relieved again. This system works very well to immediately raise the slab and close existing cracks in walls and slabs but, it does not stabilize the soil, therefore the original cause has not been corrected and raising the foundation above the soil intended to support it encourages even more evaporation. That explains why there is almost never only one piering session needed, in reality, the piering generally continues until the entire perimeter is raised above the soil allowing the shrinkage of the soil in the center of the home to shrink resulting in collapse there. Foundation repair in the center of a structure is even more invasive and expensive! Foundation experts agree that moisture stabilization is necessary to prevent further damage from reappearing. Soil Stabilization treats the cause, Piering Systems treat the symptoms.

Most homes can be equipped with a complete Moisture Stabilization System for much less than one would expect for a system that doesn’t just support here and there rather addresses the entire foundation. As an added benefit this also provides the needed moisture to any shrubs within the immediate area of the structure. Trees that are closer to the foundation than their mature height in feet may need special attention to prevent future moisture loss through root systems, we can help with that as well.

What took 5-10 years for nature to deplete, our system can replace in a few months. If you currently have a foundation problem, or you are concerned about the future of your investment, call Foundation Guard™ today—(281) 351-4600.
